IMPROVEMENT IN BUCK-SAW FRAMES.

Specification forming part of Letters Patent No. 177,243, dated May 9,1876; application filed March 20, 1576.

To all whom it may concern:

Be it known that we, ROBERT C. HAYTEN and BENJAMIN 'F. POTTER, ofYpsilanti, in the county of Washtenaw and State of Michigan, haveinvented certain new and nsefnlImprovements in Buck-Saw Frames; and wedo hereby declare that the following is a full, clear,

and exact description thereof, reference being had to the acconlpanyingdrawings, and to the letters of reference marked thereon, which formpart of this specification.

The nature of our invention consists in the construction and arrangementof aframe for buck-saws, as will be hereinafter more fully set forth.

In the annexed drawing, the figure is a side View, partly in section, ofour invention.

Our improved frame for buck-saws is composed, essentially, of two endpieces, A and B, and a center piece, O, all made of gas-pipe or tubing.The end piece A may be made of two pieces of gas-pipe or tubing, unitedby a T- joint, D, and formingat its lower end the usual handle for thiskind of saws; or this end piece may be made of a single tube, with theT- joint simply fastened thereon at the proper point to receive in itscenter arm the end of the center piece 0, which is screwed therein, andmade stationary with relation to said end piece A. The opposite end ofthe center piece 0. is formed with a tenon, a, which is inserted in ahole or slot in the end piece B. This latter piece is slotted at itslower end, and the end piece A is also slotted at a proper point toreceive the ends of the saw-blade E, which are fastened in said slots.Into the tubular center piece 0, near its stationary end, is hooked theend of a brace, G,whicl1 passes diagonally to and through the upper endof the end piece B, and a thumb-nut, J, is screwed thereon, by whichmeans it is easily and perfectly tightened, the end piece B only movingto the action of the thumb-nut.

By this arrangement of the brace the upper end of the end piece A isleft free and open, so as to be employed as a handle, if it is desiredto use both hands in manipulating the saw.

By constructing the frame entirely of gaspipe or tubing, as described,the frame is made light and cheap, while at the same time it is jointand formed with a tenon, a, at the opposite end, the end piece B,diagonal brace G, and thumb-nut J, all constructed substantially as andfor the purposes herein set forth.

In testimony that we claim the foregoing as I our own 'we affix oursignatures in presence of two witnesses.
